I’ve run out of ideas on this…. A CentOS 6 box serving nfs: two directories separately: /this/partition/dir0 and /this/partition/dir1. Everything looks good on it. On the servers it’s exporting to – two are CentOS 6, one’s CentOS 7, they all automount
/net/server/this/partition/dir0… but no matter what I’ve done, restarting autofs and nfslock, umounted things… but with autofs off, even when I manually mount it to /mnt, I get stale file handle.

The two dirs are owned by root, but one’s got a different group. Selinux settings are the same.

Clues for the poor?
